11.   The gene produces a hormone that stimulates the production of immune cells.

12.   The genes produce enzymes which convert polyphenolics, which taste sharp, into anthocyanins, which give ripe strawberries their red color.

13.   The herpes gene produces its own enzyme, known as thymidine kinase.

14.   The more difficult and time-consuming part of drug discovery is identifying the proteins produced by genes.

15.   The ob gene produces a hormone, dubbed leptin, that was reported last month to have caused dramatic weight loss in severely obese mice.

16.   The old idea that one gene produces one protein that makes something happen in the body is on the way out.

17.   The way it works is that the activated genes produce proteins, which turn off the activating genes.

18.   These biochemical signals act as volume controls, regulating how voluminously other genes produce their own molecular products.

19.   They also found that the gene produces a protein called calpain that could play a significant role in treating diabetes, Hanis said.

20.   They are produced by genes found in both animal and human chromosomes.
